I’ve had a difficult time getting my Phantom 3 to recognize the .bin files required to do a firmware update. If you run into the situation where you power-up the aircraft, with a formatted SD card and only the .bin file in the root directory, and the Phantom goes directly to writing the DCIM file and not unpacking and installing the .bin file, I believe it is because the Phantom is very finicky about the formatting of the SD card.
I’m using a MacBook Pro with a Windows 10 partition and a Sony DuoPro card reader attached by USB.
This is the procedure I followed formatting in Mac:
- Formatted the microSD card in the SD card reader using Disk Utility and the MS-DOS format
- Downloaded the .bin file from DJI
- Copied the .bin file to the microSD card in the DuoPro reader
- Ejected the microSD card
- Placed the microSD card in the Phantom and powered it up
Here is the weird part. The other choice for formatting in Disk Utility is ExFat. I couldn’t get that to work. My luck with formatting in Windows 10 to a microSD in an adapter in the SD slot on the Mac was also unsuccessful using ExFat, NTFS, and the recommended FAT32.
I can’t say for use, but not using the adapter made the difference for me.
I’ve set aside the microSD card that worked and plan to use it for all future updates. I’ve left the last version of the .bin file on the drive to make sure the new .bin file is next in the release sequence. I learned the hard way that you can’t skip an update to the Phantom firmware. If you are on 1.6 and try to update to 1.8, the update will fail.
After I have the new .bin file on the drive I delete the old file and then power-up the Phantom.
Keep Your Props Turning!
